Start with the provider category
CMS publishes the official data used by Medicare comparison websites and directories through its Provider Data Catalog. Nursing facilities, hospitals, dialysis facilities and home-health agencies are different populations; combining them requires explicit inclusion rules.
Read the dataset's definitions
Use the catalog's data dictionary for identifiers, locations, ownership and quality measures. Check reporting periods and refresh dates. A blank measure can have a specific reporting meaning; do not turn it into a zero or a poor-quality judgment.
Separate research from care decisions
A provider's presence in a research file does not establish current availability or suitability for a patient. Use Medicare Care Compare and the relevant licensing authority for the current information needed for a care decision. A directory category is not a clinical recommendation.
For outreach planning
Define whether the buyer is an operating entity, facility or location. Apply exclusions and suppression before outreach. Review the selected inventory in the list builder. Keep provider counts tied to the dataset and reporting period.
Create a provider-type-specific research sheet
Keep provider type, official identifier, facility name, location, reporting period and source together. Review the dictionary for that dataset before combining files. A shared address or similar name does not by itself establish that two records are the same provider.
Separate missing, not applicable and suppressed measures using the source’s definitions. Preserve a quality measure’s period instead of presenting it as a real-time assessment. A parent organization, operating entity and physical care location may represent different outreach targets.
Example: a directory count is not patient access
Illustrative example: a territory contains provider records in several categories. Adding them gives a combined record count only if the inclusion rules are stated; it does not measure open beds, appointment availability or suitability for a patient. Use current official comparison information and the provider for those questions.
For B2B planning, choose the facility type that actually buys your service, identify the appropriate organization and check contact relevance. Keep that commercial workflow separate from recommendations about a person’s care.
